I've been making a program and for it I need to be able to detect shutdown. I've been told to do vbAppWindows etc. but there's a problem. For some reason it says "vbAppWindows is not declared" Does anyone have another way of doing it?Then I've used my.settings throughout the program and it has just started to not work. It wont save anymore.
[Code]...
is there a way to detect if the user is shuting down?
View 1 RepliesI have an application that starts from Sub Main and I need to run a sub when the system is about to shut down, restart or logoff so it can save it's settings. I found some code on google:
Imports Microsoft.Win32
Public Sub Main
AddHandler SystemEvents.SessionEnding, AddressOf OnShuttingdown

I want to detect when employees in our company are shutting down or restarting their computers. Is there a Windows API Call that will do that which I can hook onto? I found WindowsExitEX but it actually restarts the computer!

But it doesn't seem to work, Windows shuts down yes but when I re-start the vm and run the app it opens with the old settings, not the ones that I changed before I shut down the vm. Anyone know of a way to do this or to fix the code above, I don't think my OnShuttingdown event is being handled.
I have recently made a program but while it is running the pc is unable to shutdown, i have used the followin code, so the application minimizes while closing:
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As FormClosingEventArgs) Handles Me.FormClosing
Me.Visible = False
e.Cancel = True
End Sub
Dont know if this is preventing it 0_O??? is there any alternative to this?

I'm working on a web browser named Hyvar.NET and i'd like to integrate a form of shutdown detection into it.
Currently, it simply uses a tri-option setting to decide how it opens - like this
If My.Settings.LoadLastOnStart = True Then
frm.wbTab.Navigate(My.Settings.LastOpenedPage.ToString)
ElseIf My.Settings.HomeOnStart = True Then
[Code]....
Each variable is appropriately named for its job as you can see.
However, i want to change this to react to correct and incorrect shutdowns - unexpected and user instigated ones for example. I.E: if the settings variable for the detection contained 0x000000, it could indicate a clean exit and continue as normal with a new session, but 0x000001 would indicate an unclean shutdown and present the user with an option of reopening the last session or continueing as normal, like in IE 7/8
Im 100% sure this will require a windows API call

View 3 RepliesI've written a program which I propose to give a local club, which sadly may be'attractive' to pirates so I propose to build in some sort of anti-copying feature.My idea is to hide a file in a folder somewhere in the club's laptop, then on program start up I'll check to see if that file exists and if it's not there, which it's unlikely to be on a pirates machine, I'll flag up a message box saying that if they have a legitimate reason to install the program on a different machine they'll have to contact myself.By way of nuisance value, pressing the 'OK' button on the message box will cause the machine running, what I'm assuming is a pirated copy, to shut down.I've been looking at the VB.NET forum and MSDN for ideas as to how to achieve this and the general opinion seems to be:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Process.Start("shutdown", "-s")

I have a fully working application which runs in the background while a user is logged in. What I need the application to do, is disconnect itself from the database, save the users settings and close itself when the user shuts the computer down or logs off.I know how to do those things, the issue I am facing is figuring out how to detect when the computer is logging off or shutting down. I thought about using log off scripts to do this but then it would be impossible to call classes and methods from my application as the log off scripts are not associated with my application at all. Are there any other methods of telling my application when the computer is shutting down and then run some lines of code?

View 6 RepliesI'm trying to create a way for the User of my application to Log Off, Shutdown, or Restart the PC.
The idea is that User can more quickly access these options from my application and if they choose, force these actions instead of waiting for the OS to respond.
Here's how I'm trying to do it:
CODE:
Log Off works just fine. It's shutdown and restart that doesn't work. From the research that I've done, the Consts seem fine and the function obviously works correctly because Log Off works. I am running the application as an administrator, so that should affect it.
I was woundering if there is anyway via VB.net to have only two option on vista's shutdown menu. I only need "Logoff" and "Hibernate". just woundering if there was anyway possible to have these two options.

View 26 RepliesI made a little VB app to shutdown a laptop after it has been powered on for 2 1/2 hours, and giving the user a little over 8min warning that it is about to be shutdown. However I have nothing in place to stop the user from restarting the device once it is shutdown. What I would like to integrate in this, is a sort of memory where if the user doesn't wait at least 30 minutes, the shutdwon will re-iniate immediatly.
I included the code I did so far.

I've got a List(Of IWorker) which contains a number of concretes. IWorker in turn has a Startup() and Shutdown() method.Inside the Worker class, Startup() creates a new worker thread then returns. Shutdown() presently sets a private ShutDownRequested flag and returns. The flag is checked by the worker thread (at worst every few seconds).This all works fine but at present the parent app has no way to determine if the Worker has finished shutting down.I can see a number of ways around this but am not sure what the best one is.Add a State property to IWorker. Should work but I'm going to be polling states which seems a little nasty.Make the shutdown command blocking - Would probably be my ideal solution but I'm not sure how to implement it - does the worker Sunclock a private object which Shutdown() should also try to Synclock after setting the flag?
